Abstract
An exhaust system (10) for a lean burn internal combustion engine comprises a particulate filter (12) disposed between an inlet (18) and an outlet and means (14) for deflecting at least some exhaust gas flowing in the system away from entering the filter at a point immediately opposite the inlet.
